GENEVA, SWITZERLAND / ACCESSWIRE / December 30, 2021 / RELIEF THERAPEUTICS Holding SA (SIX:RLF)(OTCQB:RLFTF)(OTCQB:RLFTY) ("Relief"), a biopharmaceutical company seeking to provide patients therapeutic relief from serious diseases with high unmet need, reported today that the parent company of its collaboration partner, NRx Pharmaceuticals, Inc. (NRXP) ("NRx"), has announced it has filed for a new Breakthrough Therapy Designation ("BTD") request with the U.S. Food and Drug Administration ("FDA") focused on patients with Critical COVID-19 and respiratory failure who are at immediate risk of death despite treatment with Remdesivir and other approved therapies. According to the press release, the BTD request is based on an FDA request for clinical data on the effectiveness of aviptadil compared to Remdesivir and other approved therapies. The press release also reported patients treated with aviptadil vs. placebo demonstrated a statistically significant (P=.03) 2.8-fold increased odds of being alive and free of respiratory failure at day 28 and day 60 and a highly significant (P=.006) four-fold increased odds of survival is seen in these patients.

ABOUT RELIEF

Relief focuses primarily on clinical-stage programs based on molecules with a history of clinical testing and use in human patients or a strong scientific rationale. Relief's lead drug candidate, RLF-100(TM) (aviptadil), a synthetic form of Vasoactive Intestinal Peptide (VIP), is in late-stage clinical testing in the U.S. for the treatment of respiratory deficiency due to COVID-19. As part of its pipeline diversification strategy, in March 2021, Relief entered into a Collaboration and License Agreement with Acer Therapeutics for the worldwide development and commercialization of ACER-001. ACER-001 is a taste-masked and immediate release proprietary powder formulation of sodium phenylbutyrate (NaPB) for the treatment of Urea Cycle Disorders and Maple Syrup Urine Disease. In addition, Relief's recently completed acquisitions of APR Applied Pharma Research SA and AdVita Lifescience GmbH, bring to Relief a diverse pipeline of marketed and development-stage programs.
